EUGENE BERCIOUX, OF PARIS, FRANCE.

CLARINET OF BOEHM.

SPECIFICATION forming part of Letters Patent No. 750,935, dated February2, 1904.

Application filed February 1'7, 1902. Serial No. 94:,369x (No model.) I

To all whom it may concern.-

Be it known that I, EUGENE BERoIoUx, a citi- Zen of the Republic ofFrance, and a resident of 91 Rue de Turenne, Paris, France, haveinvented a new and useful Improvement in Clarinets of Boehm, of whichthe following is a specification.

My invention relates to improvements in clarinets, and has for itsobject to provide mechanism for the E-flat, C, C-sharp, and B keyswhereby they may be easily and quickly manipulated by the small fingerof the player.

My invention is especially available, be-

' cause it not only is applicable to new clarinets, but also to such asare now in use without disturbing any important part of their mechanism.The four keys which are connected to this mechanism, the rock-shafts,the pads for closing the holes, and the pad-stems which connect saidpads with the rock-shafts all remain the same.

The improvement consists in dispensing with the ordinary claw-endedpiece carried by the C-key and extending under the C-sharp and B keys.This piece is very easily so much deranged that its operation ismaterially hindered, if not entirely prevented. It also is of suchconstruction that a part of the wood of the instrument has to be cutaway to provide a proper seat for it. There is no cutting away of a partof the wood necessary for the application of my improvement, and it doesnot easily get out of order.

The invention will be fully understood from the following generaldescription and the annexed drawings and will be subsequently pointedout in the claims.

In the accompanying drawings, which are hereby made a part of thisspecification, Figure 1 is a front view of the lower part of a clarinetcomprising one example of my invention, which will be more fullyhereinafter described. Fig. 2 is a sectional view taken on the line ABof Fig. 1. Fig. 3 is a front view of the lower part of a clarinetcomprising a second example of my invention. Fig. at is a sectional viewtaken on the line C D of Fig. 3.

In the drawings, 1 represents the key of E- flat, 2 represents the keyof (l, 3 represents the key of C-sharp, and 4 represents the key of B.

5 designates the rock-shaft of key 1, 6 the rock-shaft of key 2, 7 therock-shaft of key 3, and 8 the rock-shaft of key I.

In the first example of my invention (illustrated in Figs. 1 and 2) Isolder a bar 9 on the pad-stem of the rock-shaft 6, which bar isarranged parallel to the said rock-shaft 6. On the rock-shafts 7 and 8 Isolder the laterallyextending arms 10 and 11, one on each. These armsextend across the bar 9 and carry adj usting-screws 12 and 13, whichengage the said bar 9. 14, 15, and 16 designate pads for closing theholes in the clarinet. These pads are connected with the rock-shafts bypad-stems, as illustrated. All these parts are arranged as illustratedin Figs. 1 and 2. It will be observed that pads 14 and 16 areillustrated as being normally open and pad 15 as beingnormally closed.If the key 2 be depressed, it will close the pad 14: without affectingeither of the other rock-shafts or their accompanying pads. If the key 3be depressed, the pad 15 will be opened and the pad 14: closed. If thekey 4: be depressed, the pads 14: and 16 will both be closed. Thesedifferent effects are produced by the action of the bar 9 in connectionwith the arms 10 and 11, and thus the player is enabled readily tomanipulate all these parts with his small finger.

In the second example of my invention as illustrated in Figs. 3 and 4the bar 17 corresponds to the bar 9 of Fig. 1. This bar 17 I solderdirectly on the rock-shaft 6, and it is bent and arranged asillustrated, so that it will engage the laterally-extending arms 18 and19 of the rock-shafts 7 and 8. The engagement between these arms 18 and19 and the bar 17 is effected by means of the adj usting-screws 20 and21. If the key 2 be depressed, the pad 1 1 will be closed and the bar 17will rise without affecting any other part of the mechanism. If the' key3 be depressed, the pad 15 is opened and the pad 1 1 closed by thecoaction of the bar 17 and the arm 18. If the key 1 be depressed, thepad 16 will be closed, and at the same time on account of the coactionof the bar 17 and the arm 19 the pad 14 will also be closed. Thus by aslight change of arrangement, but adhering to the same principles ofconstruction, I obtain the same result in both examples of my invention.

Having now described and ascertained what my invention is and how thesame is constructed and used, what I claim as my invention, and desireto secure by Letters Patent,

1. In a clarinet, the combination with three rock-shafts, bearingsmounted on said clarinet, wherein said rock-shafts turn,laterallyextending arms carried by two of said rockshafts and keysattached to said shafts and arranged to actuate the same, of padsarranged to close openings in said clarinet, pad-stems connecting saidpads with said rock-shafts, a bar attached to said third rock-shaft,arranged to cooperate with said arms and an adjustable engagementconnecting said bar with said arms.

2. In a clarinet, the combination of a rockshaft having alaterally-extended arm, a padstem and pad, and a rock-shaft having alaterally-extended arm, pad-stem and pad and a rock-shaft having apad-stem and pad, and a bar carried by said last-named rock-shaft andarranged parallel thereto said bar adapted to cooperate with said armsof the two firstnamed rock-shafts, and two adjusting-screws engaging thesaid bar and the said arms, substantially as shown and described.

3. In a clarinet, the combination of an arm soldered to the rock-shaft 6and carrying the pad 14L corresponding to the C-key, a bar 9 secured tosaid arm, a rock-shaft 7 corresponding to the C-sharp key and providedwith an arm 10 soldered thereto and adapted to depress the bar 9, arock-shaft 8 corresponding to the B-key and provided with an arm 11soldered thereto and adapted to depress the bar 9, and adjusting-screws12 and 13 respectively carried by the arms 10 and 11, having their endsin contact with the top of thebar 5), substantially as and for thepurpose set forth.

In witness whereof I have hereunto set in y hand in presence of twowitnesses.

EUGENE BERCIOUX.
